rma-casino CUSHION Application led November 2, 1929. Serial No. 404,401.

M ed condition.

Another object of this invention is to provide an insertable ring whichmay be mounted Within a tire casing which Will not be afl'ected bynails7 glass or the like, so that the casing l5 will at all .times bemaintained in substantially undistorted condition.

y A still further object of this invention is to provide a cushioningelement insertable in a tire casing which is not subject'to punctures ,0or the like, and which may be removed from the casing When the latterhas Worn out and reinserted in another casing.

-further obj ect of this invention is to pro- `vide a device of thischaracter which will 5 eliminate the present pneumatic tubes which aremounted in tire casings and which are subject to punctures or thelike.

rEhe above and various other objects and advantages of this inventionWill in part be 50 described in and 'in part understood from thefollowing detailed description of the present preferred embodiment, vthesame being illustrated in the accompanyingdrawing Whereinz- Fig. 1 is afragmentary longitudinal section of a device constructed according tothe present invention; l

lEig. 2 is a transverse section partly in elevation, taken substantiallyon the lines 2 2 ci Fig. 1.

Fig. 3 is a fragmentary sectional view showing a niodiiication of thisdevice.

Referring to the drawing wherein like numerals designate correspondingparts throughout the drawing, the letter R designates a rim of theconventional type which may be mounted on a. Wheel or the like and whichis adapted to engage a tire casing T or the like which may be of anyconventional A cushioning element, generally designated as 10, isadapted to be removably mounted Within the tire casing T and issubstantially semi-circular-in cross section so as to substantiallyoccupy the opening or cavity Within the inner Walls of the tire casing.rl`he cushion 10 is provided with a substantially circular opening 11which is spaced inwardly from the outer surface thereof. The cushion 10may be constructed ot' any suitable material but preferably of rubber orother resilient or yieldable material. Due to the fact that the cushionis not subjected to Wear it may be constructed of Waste rubber or thelike.

rlhe cushion 1() is provided .With a plurality of arched openings 12which are preferably provided at spaced intervals about the cushion andare adapted to have their -openings extending inwardly toward the rim R.

The openings 12 are substantially tubular in shape and preferably extendabout the tubular opening 11, extending inwardly from the outer surfaceof the cushion 10, and may be of various sizes depending on the Weightto be supported.

rThrough the provision of the tubular or arched openings 12, itispossible to so regulate the resiliency of the cushion that it Willreadily support the desired Weight, this being accomplished byincreasing or decreasing the' number of openings 12 so as tocorrespondingly change the flexibility of the cushion. A plurality ofballs or spheres 13 are loosely mounted Within the tubular opening 11.rlhe balls 13 are preferably constructed of rubber or the like and inthepresent instance, the

uur)

balls 13 may be constructed of sponge rubber' or the likeso as to assistor strengthen the body structure and at the same time provide resilientcushion for the tire T when the tire engages an obstruction4 or rockprojection above the surface of the ground, or the like, over which thetire is moved. lt will be understood, however, that the cushion 10 Willsu port the tirev T Without the use of the ba ls 13.

lt will be noted from the foregoing that a substantially aeratedcushioning element is 'All provided which will sup ort the tire and atthe same time is not capable of being injured by nails or the like.

In the tire casings at present in use` an inflated tube ispositioned'within the casino' and is subject at all times to beingpunctured or injured by foreign elements, whereas in the presentinstance, a substantially firm, resilient element has been providedwhich may be inserted in any tire casing at present in use, but the useof the cushioning element will not subject the tire to undue pressurefrom within and the tire or tire casing may be worn on the wheel untilit is substantially worn out; whereas in the casings at present in use,the life of the casing has been limited to the point where it will notwithstand the pressure of the air in the inner tube in addition to theweight of the vehicle.

The use of a cushioning element of this type will therefore increase thelife orn the tire casing, eliminate the use of a spare or fifth tire,and when the outer casing has been substantially worn out, the cushionmay be reinserted in a new casing.

The inner surface li of the cushioning element l0 is preferably dat soas to conform to the conguration of the rim, and the openings l2 areadapted to extend upwardly from the dattened surface 14;.

In use, the cushion l0 may be inserted in the cwng T before mounting thecasing on the rim R and the casing may then be mounted on the rim in theusual manner, The rim R may be ot either the clincher or the straightside type. v

When the tire 'l moves forward on the ground, the lcushion l0 willyieldably cushion the tire and prevent collapsing of the tire. Dueto thelight construction of the cushion, the weight of the tire has not beensubstantially increased and at the same time a substantially yieldableiller has been provided for the tire which is not subject to dedationwhen a foreign object has pierced the walls of the casing T. lt will ofcourse be understood that the cushion l0 may he pierced by i nails orthe like, but will not be collapsed.

It is, of course, understood that various changesand modications may bemade in the details of construction and design of the above specificallydescribed embodiment of the invention without departing from the spiritthereof, such changes and modications being restricted only by the scopeof the following claims.

5;.. tire cushion insertable in a tire casing, comprising a resilientmember adapted to sulistantially ill the cavity within a tiie casing,said cushion being provided with `a circular opening spaced inwardlyfrom the outer walls thereof, and a plurality of openings spacedlymounted about4 said circular opening and open to the atmosphere at theinner periphery of the tire.

2. A tire cushion insertable in a tire casing, comprising a yieldablemember adapted to be removably mounted in a tire casing,

said member being provided with a circular opening therein, and aplurality of arcuately inclined spaced openings substantially nersurface and being provided with a circular opening positioned and spacedinwardly from the outer walls of the cushion, and a plurality of spacedopenings positioned about said circular openingv and having the outletsthereof extending through said dattened surface of said cushion, and aplura-b ity or" resilient spheres loosely mounted in said circularopening.

4t. A tire cushion insertable in a tire casing comprising a yieldablemember having a circular opening therein spaced inwardly from the outerwalls thereof, said cushion also being provided with a plurality ofradially arranged openings, sai-d openings being positioned about saidcircular opening and in spaced relation thereto, and a plurality ofyieldable members mounted in said circular opening whereby to cooperatewith the cushion to prevent collapsing of the cushion.
